I would just like to ask if there's a way to secure my Yahoo! ID information beyond passwords? What I mean is for example, Google has implemented a 2-way verification wherein, after a Google account logs in to a new computer besides the one I typically use, it requests for a validation code that it can use to verify my authenticity and thus, would send a verification code to my phone via text.

For Facebook, I set it so that if a new computer uses my Facebook account, the user will be asked to enter a computer name or identity and I will be notified that x computer signed in to my account thus giving me enough time to go online and possibly gain control of my Facebook account.
